Definitions
- the present invention relates to a stop element for at least ei ne solar module holder and in particular to a clamping clasp in order to achieve a permanent stable attachment of the solar module to a substructure.
- a problem in the attachment of solar modules by means of module clamp be is that at very high tensile loads (for example, by wind) can be a fastening tion to a substructure unstable. Thus, slipping or unscrewing of the solar module from the module terminals may occur, e.g. high suction loads act on the solar modules. This slip out of the module from the module terminals is also called a position loss net.
- the position loss depends on the module rigidity, the stiffness of the module terminal and the mounting rail. Depending on these stiffnesses, increased tensile loads result, for example, in deformation or torsion of the module and the module frame. The deformation and torsion of the module results in the frame slipping out of the module clamps, which in turn leads to higher laminate deflection. The deflection of the laminate in turn leads to an increased risk of cell breakage.
- the present invention relates to a stop element for at least ei ne solar module holder that can be attached to a substructure by Befest Trentsmit tel.
- the stop member comprises: two opposite stopper portions and at least one connecting member connecting the two opposing stopper portions.
- One of the two abutment sections is on the at least one solar module holder and the other Anschlagab section can be coupled to the fastening means or to another solar module holder to accommodate a torque caused by a load on the solar module holder. It should therefore be prevented in particular unscrewing the solar module holder from the fastening means.
- the solar module holder (s) can in particular be designed as module terminal (s) in which a solar cell module can be held by a clamping connection.
- These module clamps are connected to the substructure at several module clamping points (fixing points).
- the stop element is monolithic (eg made of a metal) and can be placed on the substructure. It can thus be loose between the sub-construction and the solar module holder. But it does not have to be monolithic. Rather, the at least one connecting element may also comprise a plurality of parts which are connectable, for example, sections with the opposite stop or have one or more cables / lines / webs can connect to the stopper sections.
- the two opposing abutment portions are formed as V-shaped sections from which len provide a stop for receiving the torque.
- the at least one connecting element can be coupled to end points of the V-shaped sections and extend laterally along the sub-construction.
- connecting elements proceed, so that the stop element forms a through opening, in which, for example, a contact point or fastening tion point between the solar module holder of the substructure can be placed.
- each stopper portion may have a respective slot to displace the stopper member along adjacent solar module holders (when inserted into the slots). The slots ensure a positive fit.
- the two opposing abutment portions and / or the connecting element Ver formed from a metal to chen ermögli an electrical potential equal between the substructure and the solar module holder.
- the present invention also relates to a solar module installation having at least one solar module; at least one solar module holder which holds the at least one solar module; a substructure, to which the at least one solar module holder is fastened together with the respective solar module; and at least one previously defined stop elements.
- the stop element may be arranged between the solar module holder and the substructure in order to prevent load-induced rotation of the solar module holder relative to the substructure.
- the stop element may be formed or arranged so that a power flow between adjacently arranged Solarmodulhalterun conditions or to the fastening means on the stop element is possible.
- Embodiments thus solve at least some of the problems mentioned above by a simple additional form-fitting connection concept between the module holders (module clamp) or to the connecting means.
- the use of the stop element makes it possible to continue to use ordinary standard module holders.
- a potential equalization can be easily integrated.
- FIG. 1A-1D show a stop element for a solar module holder after a
- FIGS. 2A-2D show a further exemplary embodiment of the stop element.
- FIGS. 3A-3D show a further exemplary embodiment of the stop element.
- FIG. 1A-1D show a stop element for two solar module holders 41, 42, which are fastened to a substructure 50 with fastening means 60.
- FIG. 1A shows a stop element which is placed on a substructure 50.
- the stop element shown comprises two opposite Anschlagab sections 111, 112, which are connected to two connecting elements 120.
- the stop element is monolithic (for example, made of a metal game). In further embodiments, however, the abutment element does not need to be monolithic.
- the Anschlagab sections 111, 112, for example, also with other dacasele elements (for example, ropes o. ⁇ .) Are connected.
- Fig. LB shows a cross-sectional view through the mounted solar module holding ments 41, 42, which are laterally supported by the two stop portions 111, 112 and mounted on the substructure 50 with fastening means 60.
- the fastening means 60 are formed between the adjacent Solarmodulhal extensions 41, 42.
- the problem solved by the invention is that as the tensile load on the fasteners 60, e.g. by a wind load on solar modules acts, a torque M on the solar module mounts 41,
- the stop element according to embodiments prevents such a rotation of the solar module holders 41, 42, as the two Anschlagab sections 111, 112 provide a stop for the solar module mounts 41, 42, which can accommodate the acting torque M.
- Fig. TC shows a plan view of the embodiment shown, wherein the loading fastening means 60 can be seen as they dulhalterept between the adjacent Solarmo 41, 42 are formed.
- Fig. TD shows a corresponding Griffinan view of the two solar module holders used 41, 42, which are held against rotation by the stop portions 111, 112 at a tensile load (in Fig. LB vertically upward).
- the stop element is essentially Chen formed as a rectangular loop, the point around the attachment between the solar module frame 41, 42 and the substructure he stretches, the V-shaped stop portions 111, 112 provide a secure stop. In this way, a permanent and stable attachment of the solar modules with the substructure - even at very high Windlastanforde ments - achieved.
- FIGS. 2A-2D show another embodiment of the present invention in which only one solar module holder 40 is inserted into the stopper member.
- Fig. 2A shows first after placing the stop member and the So larmodulhalterung 40 on the substructure 50. In the remaining space (see plan view of Fig. 2B), the fastening means 60 can be used (see space view of FIG. 2D).
- Fig. 2C finally shows a cross
- a solar module 45 is inserted into the solar module holder 40.
- the solar module 45 can be clamped in the solar module holder 40.
- the abutment portions 111, 112 again form V-shaped projections which prevent a United rotate about an axis of rotation perpendicular to the plane in Fig. 2C around by the holding together of the solar module holder 40 and the connection means 60.
- the stopper element is formed as a rectangular ge shaped plate (contour) with a rectangular opening, wherein the stop element on a line which extends, for example, centrally parallel to one of the rectangular edges, is folded.
- the stop element projects beyond a side edge of the substructure in a plan view (see FIG. 2B).
- stop element is formed in Figs. 1A-1D by further folds, which laterally edge the respective parallel rectangular edges so that they surface parallel to a surface of the substructure 50.
- the stop members between adjacent Solarmo dulhalterept 41, 42 (see Fig. 1A-1D) and to the fastening means 60 (see Fig. 2A-2D) can be formed in the same manner: by a simple folding as shown in Figs. 2A -2D or multiple folding as in Figs. 1A-1D.
- Fig. 3A-3D show a further embodiment, which differs only by the previously ge showed embodiments in that both in the Ers th stop portion 111 and in the second stop portion 112 each have a slot 113, 114 is formed.
- These slots 113, 114 are, for example, formed in such a way that they can each receive a section of the solar module holder (s) 40 after the stop element has been placed on the substructure 50 (see FIG. 3A) (see FIG.
- the embodiments with the slots have the advantage that the Anschla gelement not necessarily at an attachment point of the solar module holder 40 with the substructure 50 must be formed. Rather, the ge exposed stop member due to the slots 113, 114 are moved parallel along the neigh disclosed solar module mounts 40 and in any area a rotationally fixed connection between the solar module mounts 40 si cherstellen.
- Embodiments of the present invention thus define a simple technical solution for fast fixation of solar modules on a Unterkon construction, in which the solar modules, especially on cross-hung fats more common Steel or aluminum profiles can be attached.
- a currently existing limit for permitted module load loads can be increased and is not limited by the loss of position.
- the stop element can be used at the same time as an equipotential bonding between the solar modules and the substructure.
